How to read Mark Zuckerberg’s opening statement

Ahead of Zuckerberg’s House Energy and Commerce Committee appearance on Wednesday, his opening statement was shared (which you can read here) . In it, he takes full responsibility for recent Facebook security and privacy controversies.

“We didn’t take a broad enough view of our responsibility, and that was a big mistake,” Zuckerberg’s statement says. “It was my mistake, and I’m sorry. I started Facebook, I run it, and I’m responsible for what happens here.”

On Monday, Zuckerberg had early meetings with lawmakers including Florida Democratic Sen. Bill Nelson.

Last week, Zuckerberg confirmed he won’t be stepping down as leader of Facebook following the controversies. Zuckerberg told reporters in a lengthy Q&A session he is the best to run the social media giant, and that no one had been removed from their job in the scandal’s fallout.

“At the end of the day, this is my responsibility,” Zuckerberg said. “I’m not looking to throw anyone else under the bus.”
